Abstract

Lightning is a phenomenon that produces extraordinary power and has the potential to destroy and pose a major threat to public safety. The problem is to devise a lightning detection system capable of identifying lightning flashes. Existing lightning detection systems are typically expensive. Thus, the objective of this project is to design a low-cost lightning detection system to accurately capture lightning flashes, analyze the type of lightning flashes captured, and evaluate the performance of the system. This system was designed by developing a Fast Field buffer circuit using BUF634. Lightning detection system was fully setup by implementing Fast Field buffer circuit with parallel plated antenna to accurate detect lightning flashes. Lightning flashes data was collected within a period of one month to evaluate the characteristic and performance of the system. The system able to detect 60 negative cloud-to-ground and 51 intra-cloud lightning flashes on July 11, 2023, from 01:32:00 until 08:30:00. BUF634 and OPA633 archived 83% similarity in lightning flash detection capability. BUF634 was a 2.3 times lower peak amplitude, a 2.1 times shorter pulse duration, and 1.9 times shorter zero crossing time compared to OPA633. In conclusion, BUF634 proves capable of detecting similar types of lightning flashes, showcasing potential cost-effectiveness without compromising crucial detection capabilities.
